Spectra-Solaris Laboratory

Spectra-Solaris's set-up for solar cell spectral response, is able to measure the external and internal quantum efficiency while the cell is biased under standard (AM1.5G) illumination or monochromatic for multiple junction structures. High precision measurement is based on chopped light and independant lock-in amplifiers for device-under-test and reference detector.

Key features:

• stand-alone equipment with multiple light sources for PV measurements for spectral range 400nm to 1100nm (standard) and 300nm to 2000nm (extended)
• built accordingly to IEC 60904-8 Standard
• Flexible cell contacting (micromanipulators, tabs, etc.)
• device controled temperature: + 5 C to + 80 C (Peltier thermostat)
• dual phase precision lock-in amplifier
• very stable optical chopper (15 Hz to 30 kHz)
• 15 band pass filter wheel for rapid tests in the range 400 nm to 1100 nm
• prism monochromator based for 300 nm to 2000 nm range
• device under true short circuit condition for maximum 10 A
• transformer coupling to reject the DC component
• integrating sphere for reflectivity and transmission measurement
• cell spectral response and external quantum efficiency with bias
• cell spectral reflectivity and transmission and internal quantum efficiency
• simultaneous measurement of the cell and reference detector
• very stable Tungsten Quartz Halogen illuminator or Xenon Short Arc Discharge illuminator
• simple calibration with pyroelectric radiometer
• measurement can be performed at different operator-selected temperature
